Layoffs announced Wednesday by Dell Inc. include employees at the Lebanon plant, but company officials would not say how many workers were involved.

Company officials said Wednesday that in addition to the Lebanon plant, facilities in Nashville and worldwide were affected. The action was taken as part of the company’s continuing efforts to cut costs.

In February, Dell stopped manufacturing desktop computers at the Lebanon plant and moved some of those workers to jobs in boxing, shipping or handling at the Nashville facility. A Dell spokesman said some of those workers were among those to be laid off on Wednesday.

Although the spokesman noted that the Lebanon plant continued to operate, he would not comment on the company’s plans for the location.

Under an agreement Dell made with Wilson County when it first opened a facility here, the company must keep a certain number of employees to maintain property tax concessions.

The company also has an agreement with Nashville in which it receives $500 for each full-time worker at the end of the year.
